Industrial facilities in the United States generate and manage
about 7.6 billion tons of
nonhazardous industrial waste in land disposal units annually,
according the U.S. Environmental
Protection Agency. General Motors, however, reuses, recycles or
composts 84 percent of its worldwide
manufacturing waste and has 142 landfill-free facilities.
The landfill-free program allows GM to reduce its waste footprint,
while creating greater environmental
awareness among employees and communities where it makes and sells
cars and trucks. The GM
workforce is consistently encouraged to find new ways to operate
leaner and more efficiently.
The following summarizes GM’s blueprint for attaining landfill-free
leadership. It is intended to help
companies of all sizes and industries reduce waste and create
efficiencies.
1. Track Waste Data
Data is the backbone of any companywide zero-waste initiative. An
organization cannot manage what it
does not measure. GM uses a single resource data management system,
allowing it to best manage its
waste streams with the byproducts yielding valuable
commodities.
Waste data tracking allows a company to comprehend all materials
generated, reused and recycled.
Doing so reveals opportunities to improve and climb the
waste-reduction hierarchy. Data can be
repurposed to create specific plant goals and metrics.
Tracking data across all operations, where recycling
infrastructures may not be developed, also enables
the sharing of lessons learned.
2. Define Zero Waste
Although work is being done by various groups to standardize the
term “zero waste,” definitions can
vary across companies. According to the Zero Waste International
Alliance, businesses and communities
that achieve more than 90 percent diversion of waste from landfills
and incinerators are considered
acceptable in achieving zero waste.
GM goes further.
Maintaining a common and consistent landfill-free definition with
steps and procedures goes a long
way. The following requirements define success for GM’s
landfill-free program.
• All waste generated from ongoing, day-to-day operations,
including episodic/periodic events
such as pit cleanouts.
• Byproducts dispositioned by any method except placement in a
landfill.
• Byproduct materials sent to an off-site recycling or processing
center and subsequently
landfilled must not exceed 1 percent, by weight, of the facility’s
total annual waste production.
Ash generated from waste-to-energy recovery systems is
exempt.
Although it is desirable and recommended to recycle and reuse
byproducts of non-manufacturing event
waste such as construction, demolition and remediation materials
whenever feasible, these one-off
event materials do not count as part of daily operations.
Though construction, demolition and remediation waste is exempt
from consideration when
determining a landfill-free designation, all future GM North
American construction sites will adhere to a
process that helps reduce waste and increase energy efficiency
throughout construction. The “GM
Green Construction” program in North America aims to reduce the
weight of construction debris per
project by 90 percent through recycling and sending less to
landfill.
3. Prioritize Waste-Reduction Activities
Following are prioritized byproduct projects that enable facility
landfill-free designations.
1. Eliminating or reducing the amount of byproduct materials
2. Reusing materials onsite
3. Reusing materials externally
4. Recycling materials onsite
5. Recycling materials offsite
6. Composting either on or off site
7. Recovering the energy from materials (incineration with energy
recovery) either onsite or offsite
8. Incineration without energy recovery.
Reused waste is put to use in its original form with minimal or no
processing while recycled waste is re-
processed for a different use, such as wood pallets that are
shredded and used for wood chips or
plastics melted down and used to make other plastic parts.
GM’s 79 landfill-free manufacturing sites reuse, recycle or
compost, on average, approximately 96
percent of their waste from daily operations and convert 4 percent
to energy. The goal is to eliminate,
reuse and recycle, with expensive energy conversion being a last
resort for challenging materials.
4. Engage Employees and Build a Sustainability Culture
A key element of any waste-reduction program is the ability for
employees to envision other uses for
material. While some employees are comfortable challenging
conventional operations, leaders can
create rewards for new waste-reduction ideas and encourage
employees to develop job functions with
the environment in mind.
Finding uses for difficult-to-manage materials such as grinding
swarf, process pit sludge cleanout and
debris, filtration media, and certain scrap vehicle components can
be a challenge, but solutions can be
found when thinking creatively.
GM addressed these materials by finding or developing global
practices from subject matter experts,
peer reviews and lessons learned. The GM staff experts view data on
a regular basis and target certain
byproduct streams for innovative waste-reduction projects. The
company communicates the solutions.
and formalizes them within a web-based best practice system. GM
then tracks these best practices to
conformance and evaluates plant management teams based on their
facility’s performance to the total
waste reduction and zero-landfill goal.
Wherever possible, GM continues to make material substitutions and
process changes to improve
recyclability and design out inefficiencies. A small corporate team
oversees, coordinates and supports
the waste program to ensure both a holistic approach and the
sharing of best practices across sites.
Here are a few innovative uses for some of GM’s byproducts:
1. Converting 227 miles of oil-soaked booms off the Alabama and
Louisiana coasts from the Gulf of
Mexico oil spill into two production years’ worth of air deflectors
in the Chevrolet Volt.
2. Recycling cardboard packaging into Buick Verano headliners to
provide acoustic padding that
reduces noise in the passenger compartment.
3. Collecting more than 3.2 million water bottles from six GM
facilities and the Flint community to
recycle them into a fabric insulation that covers the Chevrolet
Equinox v6 engine to dampen
noise, an air filtration component used in 10 GM facilities, and
insulation for the Empowerment
Plan coat that transforms into a sleeping bag for the
homeless.
4. Mixing plastic caps that protect vehicle parts during shipment
with other post-consumer plastics
like bottle caps to make air deflectors for Chevrolet Silverado and
GMC Sierra pickup trucks.
5. Recycling GM test tires and tires from the Mississippi River
into the manufacturing of air and
water baffles for a variety of GM vehicles.
6. Reworking pallets to form wood beams for the homebuilding
industry.
7. Capturing solvents used between paint color changes and
reformulating them into a paint cured
and hardened with ultraviolet light and applied to plant
floors.
8. Converting 1,000 scrap Chevrolet Volt battery covers into
Scaly-sided Merganser, wood duck,
screech owl and bat nesting boxes.
9. Reusing 1,600 shipping crates as raised garden beds in a
once-abandoned parking lot for a
community garden and an urban farming initiative supporting soup
kitchens.
10. Composting food scraps from various facilities to form
nutrient-rich organic humus used as
natural fertilizer in gardens.
5. Strengthen Supplier Partnerships
As a result of its landfill-free program, GM has built a strong
network of suppliers committed to keeping
materials in their use phase. It looks for ways to recycle plant
waste into vehicle parts or plant supplies.
This type of “closed-loop” effort offers the highest form of
recycling.
GM plants hire resource managers – experts in waste elimination and
reduction – to assist. Resource
management is a strategic alternative to contemporary waste
management. GM finds it helps improve
resource efficiency through enhanced source reduction, recycling
and recovery. The contractors'
activities align with the company’s strategic goals and objectives,
and all manufacturing byproducts are
included in the program’s scope of services.
6. Resolve Regulatory Challenges
Sometimes various government regulations require disposal of
certain commodities, but solutions may
exist to avoid landfilling. In some instances, GM works with
regulatory agencies to help them
understand potential options for challenging waste streams and
discuss ways to best manage them
using sound scientific principles. Smaller companies may partner
with bigger companies to do this or
join a business association to help address challenges and generate
solutions together.
Scrapped battery covers for the Chevrolet Volt were converted into
nesting boxes for wood ducks, screech owls and bats.
Scrap aluminum shavings from machining transmission casings are
melted down and used to create more casings.
Paint sludge from GM’s Lansing Grand River plant has been turned
into plastic material and used for shipping containers durable
enough to hold Chevrolet Volt and Cruze engine components.
Solvents used between paint color changes have been reformulated
into a paint, cured and hardened with ultraviolet light, and
applied to plant floors.
Of course, not every industrial byproduct ends up generating
revenue, but it still can be useful.
250 shipping crates from one Michigan plant were turned into raised
garden beds for an urban garden in Southwest Detroit, providing
nearby residents with locally grown food.
GM donated scrap vehicle sound absorption material to help insulate
coats that transform into sleeping bags for the homeless, an
initiative led by a Detroit humanitarian.
